A group of about 50 Native Americans will ride on horseback into the Mankato area later this week. Their arrival will mark the end of a nearly 300 mile trip to mark the 146th anniversary of the largest mass execution in U.S. history. The group has endured blizzards and long stretches of below zero temperatures in their journey from the Missouri River to the Minnesota River. They saddled up again this morning in southwest Minnesota for one of the last legs of what they call a ride of reconciliation. Minnesota Public Radio's Mark Steil reports.
